A thermodynamic study on the AgSbSn system

The distribution of Ag, Co, Ni, Zn, Sn, Pb, As, Sb and Bi between calcium ferrite slag and liquid copper was measured at 1523 K under controlled CO-CO2 atmospheres. The distribution ratios, defined by %X in slag/%X in metal, were plotted against the oxygen potential and compared with those obtained for silicate slag. From the slopes of such plots, reasonable oxide forms dissolved in slag, XOν, were estimated. The increasing content of CaO in ferrite slag results in increase in the distribution ratio for As or Sb, but in decrease in the ratio for Pb. The effects of the composition change in the alloy phase and the temperature dependence on the distribution ratios were evaluated thermodynamically. It was proved that a mono-nuclear atom base expression is reasonable to express the oxide form dissolved in slag, such as CuO0.5, AsO1.5 etc. Moreover, from the iron contents in a Cu-X alloy, the interaction parameters between Fe and X in liquid copper were derived.

Distribution equilibria of minor elements between liquid copper and calcium ferrite slag

To design and develop high-temperature solder alloys, the thermodynamic calculations of phase equilibria have been performed on the binary Au-Sb and ternary Au-Sb-Sn systems over the entire composition range. The Gibbs free energy of individual phases has been approximated using a subregular-solution model, and the thermodynamic parameters for each phase have been evaluated using available experimental information on phase boundaries and other related thermodynamic properties. The calculated phase diagrams and thermodynamic quantities of the Au-Sb binary system show good agreement with experimental data, and the liquidus projection and the vertical sections in the Au-Sb-Sn ternary system are well reproduced using assessed thermodynamic parameters derived in this work.
